We compared the median survival score of BLTP2 deletion with the deletion mutants of ERBB2/HER2, a known driver of breast cancer growth44, LAMTOR1, a gene critical for mTORC1-mediated growth signalling downstream of ERBB2/HER2, and VPS13C, encoding a homologue of BLTP2. Here, BLTP2 is linked to breast carcinoma.
